A INDEX GUIDE CARD.

Application flledianuary' 25, 1928. Serial No; 249,433.

This invention relates toindex cards'and.

system to separate the cards, folders or other y index matter kconstituting the filing system.

The principal object of the invention is to provide a guide card simple and econom-` lical construction, the card having a projecting tab reinforced and protected by a sheath of transparent material constructed and arranged to permit the insertion and removal of'an index slipor label. l A

A preferred embodiment of the invention is illustrated in theraccomp-anying drawings, in which: Y Fig. 1 is a front elevation of guide card; l Y

Fig. 2 is a rear view of'said card; Fig. 3is an enlarged transverse section on the line 3 3 of Fig. 1; and

*Figa 4c is a view similar to Fig. 1 illustrating a type of connected index slips which may be employed with the improved tab.

The card body 5 may be made ofany suitably stiff sheet material, such as card-V board, fiberboard or 4stout paper, and has an integral proJecting tab 6 vand a` cover sheet or sheath of' transparent material,- such as celluloid, which is folded over the top edge of the tab at 7 to provide frontv and rear flaps 8 and 9, respectively. The vertical edges' and shoulders of the sheath preferably register with the edges of the card tab, to protect the cardv from wear. The rear i flap 9 is fastened to the back facevof the card and card tab by arsuitable adhesive 10 which is applied over the entire surface of the flap and securely unites the flap 'to thecard.

The front flap 8 extends downwardly from the fold 7 over the face of the card tab andhas its lower portion, which'preferably reaches below thebottom `edge. of the rear flap 9, adhesively secured, as indicated at 12 (Fig. 3), to the card body, leaving the upper portion thereof free from the card surface to provide a label-receiving pocket. A slit 11, preferably extending longitudinally of the card and spaced below theupper cardv edge at the bottom of said pocket, is provided in the flap `-8 to permit the insertion and removal of the label;v and smallv eyelets 14 are preferably provided through the free portion of the front flap, the card andthe rear the improved flap tohold the margins of the pocket forming portion of the flap against the card and its tab, thereby to yclose the endsI of the pocket and presssaid pocket-forming portion towardy the ycard surface frictionallyy .to hold the 'labell 15 within the pocket. v

In order that thek label may quickly andv conveniently be ,insertedr through the slit 11,

the front iiap 8 may, if desired, be formed 4with molded shoulders 13 disposed adjacent the ends of the slitV which tend to hold the mouth of the pocletlopen. ,While the eyelets 1d will tend to depressthe free portion f of the flap 8, it will be found that the provision of such fastening means does not yappreciably fiatten the raised shoulders nor ribs 18 against the `card surface. The celluloid will be bent toward the card frictionally to hold the label within the pocket; but the shoulders at the bottom of the free portion will be preserved in the form of raised ribs.

The label 15 may readily be inserted t" through the slit'11 and pushed upwardlyy until its top edge approximately coincides with the upper edge ofthe card tab 6, thus permitting the use of a large label and affording'better visibility of the index data inscribed thereon.V Y The lower margin of the label lies flatwise upon the card surface with its lower edge protected from external contacts by the thickness of the celluloid -at, the

vbottom of the-slit. VNotches 16, 17 may be provided to permit the label to be removedr by the fingers., f

The label may be a unitary slip of paper, or it may form part of an elongate strip of interconnected labels, as illustrated in Fig. 4, which shows a series of individual labels 18 connected at the perforated lines 19. The vendr label maybe inserted in the sheath pocket and vmay readilyv be torn from the` i adjacent section at the perforations. v

An index guide eard constructed as above described is economical to manufacture, durable in use and is attractive in appearance; the transparent sheath reinforces the card taband protects the tab and the adjacent card body from soilage and wear, and pro- Y ,vides a'smooth, roiiinded upper edge at the top of the tab which is agreeable tothe touch of the user; andthe construction of the label pocket permits the-label to be inserted with ease, and to be pushed upwardly to the top of the tab, and to be adjusted in the desired position by hand; Vyet by fricy tional contact'holds the label against accidental removal, and prevents the protrusion of the sides oi' the label from the-pociret.

of structure may be varied without departing from the spirit of the invention as delined in 'the appended claims.
